There are many factors that affect the quality of high-barrier stretch film processing, printing is one of them, so how to control the printing quality of stretch film?
Control the printing environment when processing high-barrier stretch film. The changes in temperature and humidity in the printing workshop have a certain effect on the substrate materials and the function of the ink. Too dry the environment will cause static electricity on the film and cause printing difficulties. Make the ink dry and not full, affecting the firmness of the ink layer.
Therefore, the ambient temperature and absolute humidity in the high-barrier stretch film printing workshop should be strictly controlled, try to keep it absolutely constant, and ensure good ventilation to increase the incidence of printing defects. Generally speaking, the temperature control in the workshop It is suitable between 18 ℃ ～ 25 ℃, and the absolute humidity should be between 60% ～ 70%.
In the printing process of high-barrier stretched film, in addition to the environment has a great impact on the printing quality, the dye quality has a great impact on the printing quality.
